To get the best performance of your boat, you will need to have the right prop. Irrespective of whether you are skiing or you are cruising, always ensure that your propeller can match the application as this will help maximize the performance of the boat by maximizing the power of your engine. When you are buying a boat’s prop, ensure that consider the following tips, as they will help you increase the efficiency, speed, and power of the engine.
A boat propeller will have a hub which will come surrounded with blades which are built in the same length and size while they are also twisted as a measure to ensure that they will be pushing water to the rears when they are turning. When water is pushed to the rears; your boat moves forward. When you are viewing the blades from the rear, you will notice that most rotate in clockwise directions although some boats will have two propellers where the propellers rotating in the anticlockwise direction help stabilize your boat and also ensure that you reduce your steering effort.
Propellers are described in two numbers which represent the diameter of the propeller and its pitch. Diameter describes the distance between the tips of your propeller’s blades and it is advisable that one selects a propeller that has a large diameter as it will help them push large volumes of water behind and create more power to move your boat. The manufacturer predetermines the diameter, and thus you will be selecting your boat’s propeller focusing on the pitch.
When you are selecting boat prop, with focus on the pitch, it is advisable that you select a prop with a higher pitch which will help move your boat faster. Low pitched props will help create more power for your boat due to high engine RPMs, but it will cause your boat to move slower. Always ensure that an engine prop that you select will help your engine operate in the set range since going under-range will lug your boat while going over-range causes your engine to strain.
When you are buying a propeller for your boat, you will also need to choose one having considered the prop rake which is the angle between the hub and the blades. It is the rake angle that determines how much bow your propeller lifts out of water and too much rake will work to strain the engine and thus affect performance of your boat.
When you are buying a prop, some will come with prop cups which will help create some space between the blade sides which serves to reduce ventilation and slippage as well. Selecting props with cups ensure that pitch size is increased and thus your engine can have more power while you can also select propellers with fewer blades as they are efficient.
